Suppose that researchers wanted to examine the combined effects of an introduced predator (a trout) and the trematode parasite Ribeiroia on amphibian populations. To do this, they
established frog populations in each of 40 artificial ponds. Each pond was assigned at random to one of four treatments (10 ponds per treatment): 1) neither trout or parasites were added
to the pond (the "No trout, no parasite" treatment); 2) no trout were added but parasites were added ("No trout, parasite added"); 3) trout were added but parasites were not added ("Trout
added, no parasite"); and 4) both trout and parasites were added ("Trout added, parasite added"). Each pond contained refugia where tadpoles could avoid attack by trout, to avoid fish
predators driving frog populations to extinction in an artificial pond, unlike what typically occurs in a natural pond. After two breeding seasons, the researchers estimated the density of
frogs in each pond. The results are shown in the table and the figure.…

- Red-billed oxpeckers feed almost exclusively on what they can collect from the skin of large African mammals. This includes ticks and other ectoparasites, but also dead skin and blood of the mammal. The attached image shows a red-billed oxpecker sitting on the back of a warthog with a tick in its bill. A recent study found that the depletion of African mammals due to habitat loss and hunting leads to declines in oxpeckers. Researchers were interested in whether the nature of the interaction between African mammals and oxpeckers was context-dependent. They compared the effect of removal of oxpeckers in two areas in which the number of ticks on the mammals differed. In area 2, stomach content data of oxpeckers showed they consumed ~400 ticks per day. Cows were infested experimentally with large numbers of tick larvae and then oxpeckers were introduced at different stages in the tick life cycle (larvae; nymph; adult). They counted the number of adult ticks that dropped off the…arrow_forwardRed-billed oxpeckers feed almost exclusively on what they can collect from the skin of large African mammals.

One has bright red and yellow stripes, the other is a nondescript greenish color. You hypothesize that the two species have adopted different antipredation strategies. 1) What would these two strategies be called? 2) Which species would you predict is noxious to potential predators and which species is palatable? 3) Which species would you predict would alter its behavior more in the presence of predators? Why?arrow_forward

Read over the information on what's happening with the study of lionfish (you can ignore the questions on this page). Answer the question here on Canvas. 18)Based on what you've learned about the invasive lionfish population in the Atlantic, and the various types of factors that may limit population growth, which ONE factor (intraspecific competition, interspecific predation, disease & parasites, social behavior) do you think would be the MOST limiting?

Wild female salmon tend to produce fewer large eggs because the large eggs contain more nutrients for the off spring, giving each individual a greater chance to survive. After just a few generations, however, captive-bred females now lay greater numbers of small eggs. Suggest a possible adaptive advantage for many small eggs in the captive-bred environment. What would you predict regarding the reproductive success of captive-bred females released in the wild?arrow_forwardWhat scientific evidence is there for the cause(s) of the decrease in the population of sea turtles?arrow_forward

(B) What is it about the mating system of Eusocial hymenoptera that Hamilton used to explain the evolution of Eusocial behavior in this insect group? (C) Eusocial behavior has evolved in non-hymenoptera. The explanation depends on unique features of the ecology of these organisms. What might these be?
